How has the traditional use of wind and water energy been modified for our convenience?

Wind and water both are the vital sources of energy. Developments and technology has brought new trends.

Windmills

We have seen windmills installed in the windy places. Let us know how people used them before and how they use them now

Earlier

Earlier, the windmills were used to harness wind energy to do mechanical work such as lifting/drawing water from a well.

Present-day

Today, windmills are used to generate electricity. In windmills, the kinetic energy of wind is harnessed and converted into electricity.

Water

We can see water everywhere but not much freshwater is available to drink. The use of water has also bee changed since olden days.

Earlier

Water only for drinking, washing and other daily chores.

Present day

Water energy which was used for transportation before is now a good source to generate electricity. Dams have been constructed on the river for generating electricity. Waterfalls were used as a source of potential energy which was converted to electricity with the help of turbines.
